SUMMARY

The disclosure provides a display apparatus which exhibits good reliability and may be disassembled and assembled conveniently.

The disclosure provides a display apparatus including a first display and a second display. The first display includes a first display body, and the first display body has a first side, a positioning recess located at the first side, and an engagement recess located in the positioning recess. The second display is detachably mounted at one side of the first display body. The second display includes a second display body, a positioning protrusion, and a pendulum hook, and the second display body has a second side. The positioning protrusion is connected to the second side, and the positioning protrusion has a cavity configured to accommodate the pendulum hook. The pendulum hook is pivotally connected to the positioning protrusion. The pendulum hook has an engagement protrusion. The positioning protrusion is inserted into the positioning recess, and the second side of the second display body contacts the first side of the first display body. The engagement protrusion of the pendulum hook is configured to move out of the cavity and be engaged with the engagement recess or move away from the engagement recess and move back to the cavity.

To sum up, in the display apparatus provided by the disclosure, as the positioning protrusion is matched with the positioning recess, the second display may be mounted at one side of the first display by the user, and the second display is also prevented from being slidably detached from the first display. Further, after the positioning protrusion is inserted into the positioning recess, and the second side of the second display body contacts the first side of the first display body. When the pendulum hook is subjected to the action of gravity so that engagement protrusion is engaged with the engagement recess, structural interference is generated between the engagement protrusion and the engagement recess, so that the second display is accordingly prevented from being detached from the first display, and assembly reliability of the display apparatus is enhanced. In contrast, when the pendulum hook is subjected to the action of gravity so that the engagement protrusion moves out of the engagement recess, the structural interference between the engagement protrusion and the engagement recess is lifted, and that the second display may be detached from the first display by the user, and easy detaching and mounting is provided.

Note that the numbers of the second magnet 123, the positioning protrusion 124, and the pendulum hook 125 may be increased or decreased according to actual needs and are not limited by the disclosure.

As shown in FIG. 1B, each positioning protrusion 124 has a cavity 124 a configured to accommodate the pendulum hook 125. The pendulum hook 125 is pivotally connected to the positioning protrusion 124 to rotate (or swing) with respect to the positioning protrusion 124 under the action of gravity. As shown in FIG. 1A and FIG. 1B, each second positioning group 1201 and one first positioning group 1101 are correspondingly arranged and are matched. To be specific, each pendulum hook 125 has an engagement protrusion 125 a matched with the corresponding engagement recess 111 c. In the state shown in FIG. 1B, each engagement protrusion 125 a is held in the corresponding cavity 124 a.

As shown in FIG. 1A and FIG. 1B, when each engagement protrusion 125 a is held in the corresponding cavity 124 a, each positioning protrusion 124 may be smoothly inserted into the corresponding positioning recess 111 b, and that the second display 120 may be mounted at one side of the first display 110.

FIG. 2A is a schematic front view of the display apparatus according to an embodiment of the disclosure. FIG. 2B is a schematic cross-sectional enlargement view taken along a cross-sectional line I-I of FIG. 2A. FIG. 3A is a schematic top view of the display apparatus of FIG. 2A. FIG. 3B is a schematic cross-sectional enlargement view taken along a cross-sectional line J-J of FIG. 3A. With reference to FIG. 2A and FIG. 3A, when the second display 120 is mounted at one side of the first display 110, the second side 121 a of the second display body 121 contacts the first side 111 a of the first display body 111.

With reference to FIG. 2B and FIG. 3B, as each second magnet 123 is matched with the corresponding first magnet 113 and each positioning protrusion 124 is matched with the corresponding positioning recess 111 b, the second display 120 may be mounted and positioned at one side of the first display 110 by the user. Further, based on magnetic attraction between each second magnet 123 and the corresponding first magnet 113 and structural interference between each positioning protrusion 124 and the corresponding positioning recess 111 b, the second display 120 and the first display 110 may not be slidably detached from each other easily. That is, each second magnet 123 and the corresponding first magnet 113 may provide a guiding and position mechanism, so that mounting may be conveniently performed, and enhanced reliability is provided. Similarly, each positioning protrusion 124 and the corresponding positioning recess 111 b may provide a guiding and positioning mechanism, so that mounting may be conveniently performed, and enhanced reliability is provided.

As shown in FIG. 3B, each positioning protrusion 124 is inserted into the corresponding positioning recess 111 b, and the second side 121 a of the second display body 121 contacts the first side 111 a of the first display body 111. Besides, the second connector 122 is connected to and contacts the first connector 112, so that the second display 120 is electrically coupled to the first display 110 to perform signal or power transmission.

With reference to FIG. 2B, the engagement protrusion 125 a of each pendulum hook 125 moves out of the corresponding cavity 124 a and is engaged with the corresponding engagement recess 111 c to generate structural interference, so that the second display 120 is prevented from being detached from the first display 110, and assembly reliability of the display apparatus 100 is enhanced.

With reference to FIG. 1A, FIG. 1B, and FIG. 2B, in this embodiment, the first display body 111 further includes a first display surface 111 d connected to the first side 111 a. Each positioning recess 111 b has a first inner wall surface 111 e close to the first display surface 111 d and a second inner wall surface 111 f away from the first display surface 111 d. To be specific, each engagement recess 111 c is located on the second inner wall surface 111 f of the corresponding positioning recess 111 b. That is, each engagement recess 111 c is located at one side of the corresponding positioning recess 111 b away from the first display surface 111 d.

The second display body 121 further includes a second display surface 121 b connected to the second side 121 a, and each positioning protrusion 124 has an opening 124 b communicating with the cavity 124 a. To be specific, each opening 124 b is located on a movement path of the corresponding engagement protrusion 125 a and faces away from the second display surface 121 b. Therefore, the engagement protrusion 125 a of each pendulum hook 125 may move out of the cavity 124 a or move back to the cavity 124 a through the corresponding opening 124 b.

With reference to FIG. 2A and FIG. 2B, the first display surface 111 d is adjacent to the second display surface 121 b, and the two surfaces face the same direction in space. When each positioning protrusion 124 is inserted into the corresponding positioning recess 111 b, each opening 124 b is aligned with the corresponding engagement recess 111 c. Under the action of gravity, each pendulum hook 125 rotates (or swings) with respect to the positioning protrusion 124, so that each engagement protrusion 125 a moves out of the cavity 124 a through the corresponding opening 124 b and is engaged with the corresponding engagement recess 111 c.

Further, as a tilt angle of the second display 120 in space changes, a position of the engagement protrusion 125 a of each pendulum hook 125 changes. In states shown in FIG. 2A and FIG. 2B, the first display surface 111 d and the second display surface 121 b are parallel to a direction of gravity 101 or are tilted backward with respect to the direction of gravity 101. Taking a notebook computer as an example, an unfolding angle of the first display 110 may be greater than or equal to 90 degrees. Under the action of gravity, the engagement protrusion 125 a of each pendulum hook 125 moves out of the cavity 124 a through the corresponding opening 124 b and is engaged with the corresponding engagement recess 111 c.

In this embodiment, each pendulum hook 125 further includes a pivoting portion 125 b pivotally connected to the positioning protrusion 124 and a counterweight portion 125 c connected to the engagement protrusion 125 a, and the pivoting portion 125 b is away from the engagement protrusion 125 a and the counterweight portion 125 c. That is, the center of mass of each pendulum hook 125 falls on the counterweight portion 125 c and is close to the engagement protrusion 125 a. When the first display surface 111 d and the second display surface 121 b are parallel to the direction of gravity 101 or are tilted backward with respect to the direction of gravity 101, under the action of gravity, the counterweight portion 125 c of each pendulum hook 125 may drive the engagement protrusion 125 a to move out of the cavity 124 a through the corresponding opening 124 b.

As shown in FIG. 2B, each pendulum hook 125 further includes a position limiting portion 125 d, the position limiting portion 125 d is connected to the counterweight portion 125 c, and the engagement protrusion 125 a and the counterweight portion 125 c are located between the pivoting portion 125 b and the position limiting portion 125 d. Further, each positioning protrusion 124 has a stopping portion 124 c adjacent to the opening 124 b, and the position limiting portion 125 d of each pendulum hook 125 is located in the corresponding cavity 124 a and abuts against the stopping portion 124 c. Therefore, the stopping portion 124 c of each positioning protrusion 124 may be configured to determine a rotation (or swing) range of the corresponding pendulum hook 125, so that most of the blocks of the pendulum hook 125 are accommodated in the cavity 124 a.

FIG. 4A is a schematic front view of the display apparatus of FIG. 2A being tilted forward. FIG. 4B is a schematic cross-sectional enlargement view taken along a cross-sectional line K-K of FIG. 4A. In FIG. 4A and FIG. 4B, the first display surface 111 d and the second display surface 121 b are not parallel to the direction of gravity 101 and are tilted forward with respect to the direction of gravity 101. Taking a notebook computer as an example, the unfolding angle of the first display 110 may be less than or equal to 70 degrees. Under the action of gravity, the engagement protrusion 125 a of each pendulum hook 125 moves away from the corresponding engagement recess 111 c and moves back to the cavity 124 a through the corresponding opening 124 b. At this time, the position limiting portion 125 d of each pendulum hook 125 is separated from the stopping portion 124 c.

After the structural interference between the engagement protrusion 125 a of each pendulum hook 125 and the corresponding engagement recess 111 c is lifted, the second display 120 may be detached from the first display 110 by the user, so that detaching and mounting may be easily performed.

In view of the foregoing, in the display apparatus provided by the disclosure, as the positioning protrusion is matched with the positioning recess and the second magnet is matched with the first magnet, the second display may be mounted at one side of the first display by the user, and the second display is also prevented from being slidably detached from the first display. Further, after the positioning protrusion is inserted into the positioning recess, and the second side of the second display body contacts the first side of the first display body. When the pendulum hook is subjected to the action of gravity so that engagement protrusion is engaged with the engagement recess, structural interference is generated between the engagement protrusion and the engagement recess, so that the second display is accordingly prevented from being detached from the first display, and assembly reliability of the display apparatus is enhanced. In contrast, when the pendulum hook is subjected to the action of gravity so that the engagement protrusion moves out of the engagement recess, the structural interference between the engagement protrusion and the engagement recess is lifted, and that the second display may be detached from the first display by the user, and easy detaching and mounting is provided.
